Old English mangere "merchant, trader, broker," from mangian "to traffic, trade," from Proto-Germanic *mangojan (cognates: Old Saxon mangon, Old Norse mangari "monger, higgler"), from Latin mango (genitive mangonis) "dealer, trader, slave-dealer," related to mangonium "displaying of wares." Not in Watkins, but Buck (with Tucker) describes it as "one who adorns his wares to give them an appearance of greater value" and writes it is probably a loan-word based on Greek manganon "means of charming or bewitching." Used in comb. form in English since at least 12c.; since 16c. chiefly with overtones of petty and disreputable.

monger :
- Forms: mancgere, mangere, mongere, etc.
- Etymology : cognate with or formed similarly to Old Saxon mongari, Old High German mangari, mengari, Old Icelandic mangari, probably directly from classical Latin mangō, dealer, trader, with substitution of the Germanic base of the suffix -er for the Latin agent-noun suffix.

- The Gulf porpoise is now one of the rarest mammals in the world, with a global population estimated at under 100 in 2014.
= Le marsouin du Golfe de Californie est l'un des mammifères les plus rares du monde, sa population était estimée en 2014 à moins de 100.

The Old French word probably is a loan-translation of a Germanic word meaning literally "sea-hog, mere-swine," such as Old Norse mar-svin, Old High German meri-swin, Middle Dutch mereswijn "porpoise" (the last of which also was borrowed directly into French and became Modern French marsouin).

Classical Latin had a similar name, porculus marinus (in Pliny), and the notion behind the name likely is a fancied resemblance of the snout to that of a pig.

target (n.)
c. 1300, "shield," (= bouclier) diminutive of late Old English targe, from Old Frenchtarge "light shield" (= bouclier léger) (12c.), from Frankish *targa "shield," from Proto-Germanic *targ- (source also of Old High German zarga "edging, border," German zarge "border, edge, frame," Old English targe, Old Norse targa "shield, buckler"), perhaps originally "edge of a shield."
Meaning "round object to be aimed at in shooting" first recorded 1757, originally in archery, perhaps suggested by the concentric circles in both. Target-practice is from 1801. Target audience is by 1951; early reference is to Cold War psychological warfare.
